METALLIC PLATE FOR BOOTS OR SHOES.

SPECIFICATION forming part of Letters Patent No. 425,758, dated April 15, 1890.

Application filed November 21, 1889. Serial No. 331,072. (No model.) Patented in England .Tune 4, 1889.1To. 9,228.

To all whom it may concern:

Beit known that we, EDWARD DUERDEN and vJOSEPH CHEETHAM, both of Ismailovo, near Moscow, Russia, have invented a new and useful Improvement in Metallic wearin gplates for Boots or Shoes, (patented in England June 4, 1889, No. 9,228,) of which the following is a full, clear, and exact description.

This invention relates to metallic plates or patches, technically called protectors for boot and shoe heels, to prolong the wear or durability of the .heel to which said plates are applied. Such devices in different forms of construction have heretofore been used; and our invention consists in a novel construction of and means used for securing said plates in position, substantially as hereinafter described, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding.,r parts in all the figures.

Figure 1 represents an inverted'plan or under side view of a boot or shoe having our invention applied. Fig. 2 is a sectional side view of theheel part shown in Fig. 1 upon the line w w in said figure. Fig. 3 is a vertical section of a center plate used on the heel shown in Figs. 1 and 2. Fig. 4 is an inverted plan view of one of a pair of additional heel-plates for use in connection, when desired, with the circular heel-plates; Fig. 5, an inverted plan view of the outer circular heelplate detached, and Fig. 6 a transverse section of the same upon the line y y in Fig. 5. Fig. 7 is a longitudinal View of an implement that may be used to rotate the outer circular heel-plate.

A is an annular heel-plate made of any suitable metal, wrought or cast, including malleable iron o r steel, and constructed with an upper internally-proj ecting flange l) around its central space or cavity. B is a central heel wearing-plate constructed with an upper outerprojecting fiange b. These plates A and B being suitably located on the heel, the space in between them is filled in with one or more thicknesses or layers of leather or other suitable wearing material, the same constituting a filling C of soft material as compared with the plates A and B. Such filling C is secured to the under side of the heel D of the boot by means of pegs, screws, nails, or spikes c in the ordinary manner of building up the heel. The outer and inner edges of this filling C, as shown in Figs. l and 2, extend under the flanges l) l2 of the plates A B, while the portion of said filling that occupies an intermediate or central position between the plates is secured to the boot-heel proper, as hereinbefore described. In this Way the leather or other equivalent filling C serves to secure the plates A B in position upon the heel D without requiring any separate means of fastening the same. Such means of attachment enables the annular heel-plate A to be turned around a central axis independent of the fixed filling C, and the central plate B may, if desired, be similarly turned to vary the plate-surface exposed to wear, as required, so as to present a fresh wearing-surface as needed-that is, a fresh segment, for instance, of the annular plate A, as one part after another wears do\vn--and thus the entire metal plate can be used as wearing-surface.

A convenient means of turning the plate A is afforded by constructing said plate with a series of holes e and employing a tool or implement like that shown in Eig. 7, said tool S being formed with a notch f, leaving a lip g at its one end. By inserting this lip or tooth in either of the holes e and bringing the back wall of the notch into contact with the outer edge of the plate A a leverage is obtained which enables a person to turn such heelplate to any desired extent, so as to present any desired segmental portion thereof as 1vfearing-surface at any particular part of the eel.

Boots or shoes with large heels and designed for heavy wear may have arranged on the front portions of their heels additional or corner plates A2 A2 outside of the rotatable plate A. (See Fig. 1.) These additional or corner heel-plates are apertured and are provided With an upper inner flange l), and are packed with a leather filling C, that serves to hold them in place; but, in addition to the inner flange l), they are constructed with an outer flange or ledge b2, asinore clearly shown IOO in Fig. 4, and which is made to project over the annular heel-plate A, as shown in Fig. 1, whereby said corner plates A2 are more firmly held in position. a

Having thus described our iuv`ention,wl1at We claim as new, and desire to secure by Letters Patent, is-

1. The combination, with the heel ofI a boot or shoe, of the rotatable annular metallic plate A, having an internally-projectingupper flange l), the central plate B, having an eXterior upper flange b', and the filling C, of leather or other like wearing material, arranged Within the space between `the two plates and constructed to secure and support them by their respective flanges and iixedly secured to the heel ot the boot or shoe, sub-
